Abstract

fetched live from OpenAlex

It is critical to decompose mixed pixels in a <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">hyperspectral image (HSI)</i> into pure spectral signatures and fractions, known as endmembers and abundances. However, current methods usually combine all endmembers and abundances into a single matrix. However, this approach overlooks the distinct capacity differences of each substance subspace. Furthermore, traditional approaches typically reconstruct without accounting for corresponding errors, resulting in suboptimal outcomes. In this work, we introduce a novel framework that uses self-adjusted <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">individual logical feature (LIF)</i> subspaces for each substance. This enables the accurate modeling of each substance’s unique properties. Our method calculates the capacity of each subspace by unifying the features of each substance, thereby ensuring a more accurate representation. Importantly, our approach balances reconstruction fidelity and error, preventing blind approximation of the observed HSI and addressing overfitting. Additionally, our approach exploits correlations between reconstructed subspaces to minimize redundancy. Extensive experimental results on several datasets demonstrate the superior performance and validity of the proposed method.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
